I have recently purchased a 1999 Sea Hunt 172 Triton and have a concern about the transom. The previous owner is a very good friend of mine and told me before I bought the boat that when her replaced the drain plug in the transom that he noticed a small amount of wood rot. The rot only was only about 1/2 to 3/4 of an inch around all sides of the plug. When he found this he dug out all the rotted wood, filled it with 5200 and then stuck a piece of PVC in the plug orfice that fit perfectly and was very tight. This was followed by a new plug and new sealant. I was not concered when I purchased the boat as her corrected the problem. The concerns for me that have developed as should I check the other through hull fittings that are on the trasnsom for rot as well? IE: The seal between the transom and scuppers, the through hull fitting for the live well aerator pump, and any screws that are holding on the transducer and speed sensor, as well as the bolts that hold on the outboard? I am also a little concered about the aluminum cap that goes over the top of the transom where the outboard bolts down. How well are the scuppers and this cap sealed from the factory and should i go ahead and take them off and reseal them? The transom feels more than stout when you grab the foot of the motor and shake it, and seems very solid when you bang on it with your fist. I am was wondering if anyone could shed some light on the fact that the screw that held dow the bilge float switch next to the oil resivoir tank had some water coming out of it. Just want to take every precaution to stave off any future rot and stop any that has already astarted. Thanks for your advice.
